A melter, mixer and applicator system for applying coating or sealing compositions is disclosed. An internal combustion engine, such as a diesel engine, is used to provide the motive force necessary to operate many or all of the components of the system. A tank surrounded by an internal heating system is provided for melting a first material, such as asphalt. An insulated cabinet is provided and heated from heat generated by the internal heating system. The plumbing configuration for the system is disposed within the heated cabinet for mixing the material heated within the tank with an additional material fed to the plumbing configuration by a proportioner pump. The output of this mixture serves, through a heated hose, as one of the inputs to the applicator, which is preferably a plural component spray gun. The other input to the applicator is another material fed directly from the proportioner pump. The proportioner, preferably provides the two materials running through it in a predetermined ratio amount with respect to each other. A pre-heater assembly can be disposed within the heated cabinet for heating the material fed from the proportioner prior to its mixing with the material from the tank.
